All About Rifle Optics
Rifle scopes allow you to precisely aim a rifle at different targets by aligning your eye with the target at range. They do this through magnification by using a set of lenses inside the scope. The scope’s alignment can be adapted to account for different natural factors like wind speed and elevation increases to account for bullet drop.
The scope’s function is to understand precisely where the bullet will land based on the sight picture you are seeing via the scope as you line up the scope’s crosshair or reticle with the intended target. Most modern-day rifle scopes and optics have around eleven parts which are located internally and outside of the optic. These optic pieces include the rifle scope’s body, lenses, windage turrets or dials, objective focus rings, and other elements. Learn about the eleven parts of optics.
Rifle Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Choosing the best type of rifle optic is based on what type of shooting you plan to do.
First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These kinds of scopes are helpful for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where calculations are minor
- Experienced shooters who have an idea for their aim point “hold over” and “lead” relationships for their firearms
- Shooters who do not mind the reticle is enlarged and occupies more visual eyesight room than a SFP reticle
Second Focal Plane Optic Details
Second focal plane scopes (SFP) include the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance kinds of shooting where shooters have extra time to make ballistic computations
- Shooting where most shots happen within shorter ranges and distances
- Shooters who like a clearer optic sight picture without area taken up by the bigger FFP reticle
Zoom for Rifle Scopes
The measure of scope magnification you need on your glass depends upon the type of shooting you plan to do. Pretty much every style of rifle scope provides some amount of magnification. The level of magnification a scope offers is established by the size, density, and curves of the lenses within the rifle optic. The magnifying level of the scope is the “power” of the scope. This suggests what the shooter is observing through the scope is magnified times the power factor of what can normally be seen by human eyes.
About Fixed Single Power Lens Rifle Scopes
A single power rifle optic uses a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not fluctuate since it is set from the factory.
Info on Variable Power Lens Rifle Scopes
Variable power rifle scopes have adjustable power. It will list the zoom amount in a format such as 2-10×32. These numbers indicate the magnification of the scope can be set between 2x and 10x power. This additionally includes the power levels in-between 2 and 10. The power manipulation is achieved by operating the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range
Here are some suggested scope powers and the distances where they may be successfully used. Bear in mind that higher magnification glass will not be as efficient as lower powered scope and optics because excessive zoom can be a bad thing. The same concept applies to extended ranges where the shooter needs increased power to see precisely where to properly aim the rifle.
About Lens Finishing
All contemporary rifle optic and scope lenses are coated. Lens finish is an essential element of a rifle system when looking into high end rifle optics and scope systems.
Info on Scope Lens Coatings – HD Versus ED
Some rifle scope makers also use “HD” or high-definition lense coatings that make the most of different processes, rare earth compounds, elements, and polarizations to enhance a wide range of color ranges and viewable definition through lenses. This high-definition covering is commonly used with more costly high density glass which reduces light’s potential to refract by means of the lens glass. Some scope corporations use “HD” to refer to “ED” implying extra-low dispersion glass. ED handles how colors are presented on the chroma spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration may be obvious over objects with defined outlines as light hits the object from specific angles.
Single Covering Versus Multi-Coating
Various optic lenses can even have various finishings applied to them. All lenses usually have at least some kind of treatment or finish applied to them before they are used in a rifle scope or optic. This is since the lens isn’t simply a raw piece of glass. It becomes part of the finely tuned optic. It must have a finishing applied to it so that the lens will be optimally usable in lots of types of environments, degrees of sunlight (full VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is usually a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while lowering glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends upon the scope maker and just how much you spent paying for it. The scope’s maker and cost are signs of the lens quality.
Some scope producers also make it a point to define if their optic lenses are coated or “multi” covered. This suggests the lens has multiple treatments applied to them. If a lens gets numerous treatments, it can indicate that a company is taking numerous actions to fight different natural factors like an anti-glare covering, a scratch resistant anti-abrasion covering, followed by a hydrophilic finishing. This also does not necessarily mean the multi-coated lens is better than a single layered lens. Being “better” hinges on the producer’s lens treatment innovation and the quality of components used in constructing the rifle optic.
Hydrophobic Rifle Glass Lens Finishing
Water on a scope lens does not support maintaining a clear sight picture through a scope whatsoever. Many top of the line and premium scope manufacturers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It provides protection for the surface area of the Steiner scope lens so the water molecules can not bind to it or create surface tension. The outcome is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Alternatives for Mounting Scopes on Firearms
Installing approaches for scopes can be found in a few options. There are the standard scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also normally are made in quick release variations which use toss levers which allow rifle shooters to rapidly mount and remove the optics.
Hex Key Rifle Glass Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which are designed for long range accuracy shooting. This type of scope install is wonderful for rifles which require a durable, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Scope Rings
These types of quick-release rifle scope mounts can be used to quickly connect and take off a scope from a rifle before reattaching it to a different rifle. Several scopes can also be swapped out if they all use a similar style mount. These types of mounts come in handy for rifle platforms which are carried a lot, to swap out the optic from the rifle for protection, or for optics which are used between multiple rifles or are situationally focused.
Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can ruin a day of shooting and your pricey optic by causing fogging and developing residue inside of the scope tube. Most scopes prevent wetness from entering the scope tube with a system of sealing O-rings which are waterproof.
Info on Optic Tube Gas Purging
Another part of avoiding the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Given that this area is currently taken up by the gas, the glass is less altered by condition alterations and pressure distinctions from the outside environment which may potentially enable water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
